hi,

I'm using clamav-deamon with freshclam to scan incoming emails on my mail-server*

After the last clamav-update in debian etch, clamav stops working sometimes after freshclam updated the signatures. In the log-file it reads like this:

/var/log/clamav/clamav.log -->
>(..) 21:56:32 (..)SelfCheck: Database modification detected. Forcing reload.
>(..) 21:56:32 (..)Reading databases from /var/lib/clamav
>(..) 21:58:42 (..)ERROR: reload db failed: Unable to lock database directory (try 1)

>(..) 22:03:02 (..)Pid file removed.
>(..) 22:03:02 (..)--- Stopped at Wed Mar 12 22:03:02 2008
<---

Both clamd.ctl and clamd.pid in /var/run/clamav will removed, and two clamscan-processes (started by postfix) will use 99% of CPU.

A simple restart of clamd, freshclamd and postfix does not help, the only one which helps is to restart the whole server. ~10mins after restart the log is looking like:

/var/log/clamav/clamav.log -->

Here are the debian-packets I use: clamav 0.90.1dfsg-3etch10 clamav-freshclam 0.90.1dfsg-3etch10 clamav-daemon 0.90.1dfsg-3etch10 Kernel: 2.6.18-6-amd64
libc: libc6 2.3.6.ds1-13etch5
/var/lib/clamav is on an ext3-filesystem.

Has somebody an idea to solve it? Groups+Permissions of the relevant files are looking OK.

Thanks,
Markus
